Got a hydraulic setup that needs a half inch thirteen thread nut and wondering if this Permco one would hold up in a working system under pressure?

Question by: Randy H on Jul 20, 2025, 8:05 PM

Permco builds these for exactly that kind of use. The 1/2-13 threading is precision cut to hold a secure connection in hydraulic systems, and the construction is meant to maintain system integrity even when things get demanding. For assembly work or keeping an existing setup running right, it fits the bill.

got a Permco setup here. is this nut just a standard 1/2 -13 hex nut for locking down connections?

Question by: Wayne A on Jan 24, 2026, 6:53 AM

Used as a fastening piece, it threads onto a 1/2 -13 stud or bolt to secure and stabilize a connection. In hydraulic and other industrial assemblies, that snug fit helps keep joints from loosening and supports overall system integrity.

What size wrench do I need for this nut?

This Permco hex nut is made to fit a 1/2 -13 thread, which is a pretty standard size for a lot of hydraulic applications.
